All Harmony SPI demos fail on a PIC32MZ EF SK

 


Hi,
I have a PIC32MZ EF Starter Kit, and am trying to get a SPI example from Harmony working.
I am using MPLABX v5.05, XC32 v2.10, and Harmony v2.06.
I tried the spi_loopback and spi_self_loopback projects in the Harmony apps/ folder and they both compile fine but they both fail the demo app with 0xfffffff in the rx buffer.
The only unusual thing I see is the below warning I get every time I program the dev board, but other harmony examples (such as the nvm driver demo) work just fine with the same warning:
"Target Device ID (0x7227053) is an Invalid Device ID. Please check your connections to the Target Device."
 
Any help is very appreciated.

    Then you don't have the CPU you tell the compiler that you have.
    Double check and with the MZ series, I'd have a very close look at the data sheet for mask revisions and CPU-IDs.

    Nick,
     
    I had PIC32MZ2048EFM144 selected in project properties instead of PIC32MZ2048EFH144. I corrected that and now it programs without warnings. Thanks for your help.
     
    But the SPI problem is still there: RX data is all 0xFFs..
